In the control strategy , the basic value of rotation rate is calculated by corrected similar formulation and the adjustment value is ascertained by output of fuzzy controllers , the strategy can assure steady precision and to eliminate vibration 在这种控制策略中转速控制量的基值根据修正后的相似公式进行计算,而转速控制量的调节值为模糊控制器的输出,这样做既保证了系统的稳态精度;也避免了系统振荡。
In solving npc problems , the development of complete polynomial time approximation scheme for 0 - 1 knapsack problem is the most successful example , the thesis analyzes the common points between the scheme and algorithm1 ( being in practice ) , 2 , then describes the key factors influencing the performances of the algorithm 1 , 2 , which provide a good approach to instruct the improvement and application of ec optimization . due to the complex mutual - influences between pc and ec , the global optimal tsc is even much more difficult 文中阐述了算法1 、 2 (现有实用的紧急控制寻优算法和本文构造的算法)与之的相通之处,指出寻优初始基值策略是影响算法1 、 2性能的关键因素,而算法1则是算法2在基值选择策略上的一种细化,为指导紧急控制优化算法进一步改善和应用提供了很好的思路。
The paper analyzes the main reason of causing system oscillation when it is adjusted by original pid control method , and proposes control strategy of combining basic value of rotation rate with adjustment value to control pump rotation speed according to non - linear characteristic of the system and control request 本文分析了原pid控制方案导致系统剧烈振荡的主要原因,并且针对系统的非线性特点和系统控制要求,提出了将控制量基值与调节值相结合实现对输油泵系统控制的控制策略。
In this paper , the upper - class intelligent control scheme is adopted according to the characteristics of tobacco re - dryer and the present control condition in order to solve the problem that the output tobacco moisture can ? keep stable . that is , to keep the old every pid control link , to add the upper - class computer so that sets up the upper - class intelligent control system that consists of the description management sub - system , the fuzzy compensation on line sub - system and the self - learning system . the following are control procedure : first of all , a series of output values of description can be obtained by the forward inference of basic controller on the basis of the information of input tobacco , then , these output values can be adjusted by the fuzzy compensation controller with inquiring the fuzzy control - list on line in the light of the output tobacco moisture error 本文针对烤机的工艺特点和目前控制现状,提出用上位智能控制的方法解决烤机目前存在的问题,即在保留原有各段pid控制的基础上,增加上位计算机,建立起由配方管理子系统、模糊在线修正子系统和自学习系统组成的上位计算机监控、决策的智能控制系统;控制过程为:基本配方控制器根据来料信息正向推理提供烟叶复烤机各段参数设定值的基值;模糊补偿控制器根据烟叶水分偏差在线查询模糊控制表提供相应参数设定值的修正值,实现烟叶复烤机参数的在线修正;学习环节的引入实现烟叶配方的在线优化。
